Hi all, We are going to undertake a project on "Implementation of a Voice Channel Mixer using DSP". In this project,we try to conference 2 or more voice channels.These voice channels are first converted into digital(using A/D).Then they are digitally mixed and reproduced at the user-end(D/A is done here). Here we propose to implement this Digital MIXER using DSP. As we are new to DSP,we require some help. For this,I have a few queries on the MINIMUM Requirements(equipments) for this... 1) Is Fixed point DSP sufficient to implement this or Is a floating point DSP required? 2) What is the minimum RAM that we require in the DSP Kit(we should buy)to implment/run this Mixer code? 3) Is the C5416 DSP Starter Kit enough to do our project? (http://focus.ti.com/docs/prod/productfolder.jhtml?genericPartNumber=TMS320VC5416) Please give your suggestions,which would help us in starting the project, as we have not yet decided which Kit to buy so far........ Thanks in advance, Prakash.

Most speech applications are done this way. We have products that may be very suitable for your application. Our DSP-8300 modules consist of an ADI ADSP-2186M, a stereo AC'97 audio codec, and a flash based loader. Details are on our web site.
